Latest TrickBot's appearances

TrickBot's update came in March 2018, when hackers improved the code by making its detection and defense more complicated.

It has also been utilized to provide screen-locking capabilities, working similarly to ransomware. However, it seems that this aspect of the virus is not fully developed yet, as the module that is meant to encrypt files does not accomplish its goal.

In May same year, security researchers noted a collaboration of two viruses - TrickBot and IcedID. While most Trojans would usually remove previously installed malware, authors of these malicious threats decided to work together and share profits. Apparently, computers infected with IcedID were also injected with TrickBot, making the operation of malware much more efficient.

In June 2018, TrickBot targeted UK citizens, sending them spoofing HM Revenue & Customs emails, which claimed that there is an outstanding amount of money that victims need to pay back. Users were then prompted to click on a malicious link or on the attachment, which delivered TrickBot malware.

In 2019, Trickbot was seen in several campaigns that were also infecting users with such threats as Ryuk ransomware or Emotet. In summer, more than 250 million email accounts were compromised by the malware, sending out malspam to other targets worldwide.

Additionally, security experts also noticed several updates to TrickBot during 2019, including its "TrichBooster" module that allows the exploitation of SMB (Server Message Block) vulnerability in order to send spam and avoid detection from deleting sent emails from the outbox.

During the 2020 COVID-19 pandemic, TrickBot was also employed in malicious coronavirus-themed spam emails, where the attackers use WHO (World Health Organization) and other entities. Security experts are warning organizations that more variations of phishing emails are targeting companies and businesses with TrickBot and other malware:

TrickBot - a modular banking malware employed by criminals in different campaigns to steal sensitive data

TrickBot is a financial Trojan first discovered in 2016 and targeted customers of leading banks in the UK, US, Australia, and other countries.

The virus is well-known for its ability to mimic online banking windows and steal personal information, such as log-in names and passwords, with the help of the post-exploitation tool Mimikatz. It is also capable of stealing information from Bitcoin wallets, acquiring access to email accounts and stealing network/system data to proliferate laterally. Additionally, the compromised system might start sending spam emails boobytrapped with Trickbot's payload.

Analysts revealed that this malicious program was invented and released to the cyberspace after cybercriminals noticed the significant success of Dyre trojan , and began using it as malware-as-a-service.TrickBot was actively performing attacks on CRMs (Customer relationship management) and Payment Processors, and over the years, has seen a variety of malspam campaigns.

In 2019, malware managed to hijack 250 million email accounts to increase its operations. During the coronavirus pandemic, cybercriminals behind Trick bot virus employed medical advice and testing lures to make users click on attachments and execute malicious macro commands.

Analysis revealed that this banking Trojan employs similar encryption techniques and hijack strategies as Dyre (alternatively known as Dyreza). Malware can bypass some security applications and infiltrates the system when users click on the malicious link or download a fake program.

After the invasion, TrickBot injects its malicious scripts and codes into banking websites. In other words, the cyber threat switches the original version of the site with its malignant substitute. In order to enforce this technique, C encryption language is used. In this regard, the newly detected Trick Bot malware also uses the improved version of the algorithm – C++.

What is more, the technique is supplemented with Microsoft CryptoAPI algorithm unlike AES and SHA256, previously employed by Dyre. Unlike the previous version of the virus, Trojan.TrickBot executes COM and TaskScheduler commands to maintain the computer under control.

The first campaigns were targeted Australian banks only. However, on April 2017 TrickBot Trojan has been spotted attacking banks in The United States, Canada, United Kingdom, Ireland, Germany, France, Switzerland, and New Zealand.

While TrickBot Trojan mainly targets corporate networks and businesses, regular users might encounter it as well. In case of the attack, you need to run a full system scan with a reputable malware removal program, such as or . It will help to remove TrickBot from the system entirely.

Due to excessive malware's capabilities, systems that the infection occurred on might struggle to operate properly, even after TrickBot removal.

Criminals released a test version of the password-stealing grabber.dll module by mistake

In the first half of July 2020, cybersecurity researcher Vitaly Kremez shared the news about the infamous credential-stealer TrickBot on Twitter.

In fact, it turns out that the managers of this deadly dangerous Trojan failed to initiate their latest attack. According to the researcher, crooks released a test module of password-stealing grabber.dll, which once installed informs the victim via the default web browser that the system has been infected. Google Chrome, Mozilla Firefox, Internet Explorer, Microsoft Edge, Opera, and users of other web browsers started reporting the following message last week:

TrickBot trojan is being distributed via spam email attachments and, usually, initiates its malicious activities in a way to remain unnoticed. Thus, the above message showing up on web browsers indicates the fact that it's the first time when criminals failed and the current campaign is not going to be very successful.

The notification saying "the program named grabber gathered some information from your browser" is genuine. It's not a scam as many consider it. The alert is triggered by the grabber.dll, which is one of the main TrickBot virus executables aiming at harvesting saved passwords and browser credentials. In case of success, the virus gets all credentials that are required for the connection to the victim's bank account or other accounts.

People who have received the notification about "program named grabber" while web browsing must immediately close the browser, restart the machine into Safe Mode, and run a full system scan with a professional anti-malware program. This notification means that a TrickBot Grabber has been recently installed and has to be removed to prevent data leakage, identity theft, and money loss.

Fake Lloyd's bank emails help to distribute Trick Bot

Experts have recently spotted a new way which was employed to distribute TrickBot trojan.

The malware was spreading inside the email letters from fake Lloyds Bank . It was disguised as an attachment holding confidential account documents. Note that official Lloyds Bank is not related to this malspam campaign in any way, except that its name was used for malevolent purposes.

Victims report receiving an email from <secure@lloyds-commercial.com> on December 6, 2017, which contained Protected32.doc attachments. Obviously, the letter was designed to look extremely genuine and has convinced many people to believe its legitimacy.

The email briefly explained to the recipients that it is an automatically sent message which does not require a reply. It simply encouraged the gullible people to check the attachment and included the following instructions:

Remember, that you should not open any email attachments which look suspicious or unrelated to you. We want to remind you about the previous techniques which hackers used to spread TrickBot malware. The hackers have tried to employ a similar malspam campaign in June 2017 which was almost identical to the one spreading Jaff ransomware.

Cybercriminals used social engineering techniques to trick users into opening a malicious email attachment. They included an obfuscated PDF file that opens a Word document.

This file asked to enable macro command in order to see the content. Clicking "Enable Macros" button executes Trojan on the system. New victims of TrickBot were banks in India, Singapore, Netherlands, and Bulgaria.

However, financial institutions were not the only ones who have been suffering from TrickBot Trojan. Now it is also targeting two Customer Relationship Manager (CRM) SaaS providers and PayPal users. In May security researchers discovered two malware distribution campaigns that targeted 210 URLs.

Trojan has mostly been spread via phishing emails

Experts have detected that phishing emails are still the primary distribution method used by hackers to infiltrate TrickBo .

They might disguise under genuine looking PDF or DOC documents and contain Invoice or Private Details subject line. People are easily tricked to open malicious attachments since criminals imitate well-known companies.

Malware also aims at PayPal users. Thus, if you receive an email from PayPal about suspicious activities in your account or reporting about other problems, you should login into their website directly instead of clicking provided links or attached documents.

The crooks develop different techniques to access personal information. Thus, such emails are usually very convincing. Do not fall into their trap even if they ask you to review suspicious invoice documents or tax reports.

Furthermore, the Trojan can attach itself to a free application. So you should give it a second thought before installing even a new media player. The latter often happens to be the carrier of more malicious cyber threats. By exercising additional caution, you will reduce the probability of TrickBot hijack.
